I've had a strange file appear in MegaUpload (https://mega.co.nz) drive. I haven't used the service since last year, but I wanted to make a file available today and noticed this file in the root folder. "Bertie Botts - Doo Bidee Doo Bidee Doo.rar" (122mb) which was uploaded on 2013-05-16 (recently).

I've googled and it seems this wasn't reported by anyone else. What do you think has happened? Conspiracy theories welcome

Edit: Looking at my session history, my last one was 2013-01-25 21:10.
